In this paper, a new multi-antenna CC scheme is introduced for efficient content delivery in wireless access networks with location-dependent content requests. This work is a non-trivial extension of our earlier paper [1]} now applied to multi-antenna setups. We consider a wireless connectivity scenario where the users are free to move and their requested contents depend on their instant locations. A multi-user immersive viewing environment is considered as a specific use-case, where several users are submerged into a network-based immersive application that runs on high-end eyewears. Such a use case entails a substantial volume of multimedia traffic with guaranteed quality of experience (QoE) throughout the operating environment. To this end, a location-dependent uneven memory allocation similar to [1]} is first carried out. Conventional CC delivery schemes cannot be applied anymore since users in different locations have distinct caching ratios due to uneven cache placement. Therefore, a novel packet generation scheme is devised to handle the anomaly by creating packets with size proportional to the corresponding uneven cache ratios. Finally, a novel multicast beamforming scheme with an underlying multi-rate modulation is proposed to leverage aggregate global caching and multiplexing gains simultaneously. The proposed scheme improves QoE compared to the state-of-the-art.
